#### Answer:

We needs approx.

#### Explanation:

Your first step is to write a stoichiometric equation.....this is absolutely vital.

This is a comproportionation reaction, in which nitrogen is simultaneously oxidized (from

And given the clear stoichiometry, each equiv dinitrogen gas corresponds to one equiv of

Now, given the Ideal gas equation, and we may reasonably assume ideality, then

And thus there were about

And thus there were

And we use these data to tell us that

And so we needs

Are you with me? I urge you to go thru the equations yourself, and reproduce it (and you might find an error on my part). Part of the problem is that your question assumed knowledge of data that were not quoted in the question. (These data should have been quoted!).
